Although a classification for mastocytosis and diagnostic criteria are available, there remains a need to define standards for the application of diagnostic tests, clinical evaluations, and treatment responses. To address these demands, leading experts discussed current issues and standards in mastocytosis in a Working Conference. The present article(More)
BACKGROUND Recent data indicate that fungi may contribute to increased severity of asthma. OBJECTIVES To determine the prevalence of allergy to 15 mold allergens among patients hospitalized because of exacerbation of asthma and to evaluate the relationship between the severity of the disease and allergy to particular molds. METHODS Skin prick tests with(More)
The most important causative factor for anaphylaxis in mastocytosis are insect stings. The purpose of this review is to analyse the available data concerning prevalence, diagnosis, safety and effectiveness of venom immunotherapy (VIT) in mastocytosis patients. If data were unclear, authors were contacted personally for further information. Quality of(More)
BACKGROUND Anaphylaxis to insect venom (Hymenoptera) is most severe in patients with mastocytosis and may even lead to death. However, not all patients with mastocytosis suffer from anaphylaxis. The aim of the study was to analyze differences in gene expression between patients with indolent systemic mastocytosis (ISM) and a history of insect venom(More)
OBJECTIVE We report the rare family in which cutaneous mastocytosis was diagnosed in the father and two children, with urticaria pigmentosa as the only manifestation of the disease. The diagnosis of mastocytosis in the father included bone marrow histopathological and cytological examinations and flow cytometry, and histopathological examination of the(More)
BACKGROUND Mastocytosis is a heterogenous disease involving mast cells (MC) and their progenitors. Cutaneous and systemic variants of the disease have been reported. In contrast to cutaneous mastocytosis (CM), patients with systemic mastocytosis (SM) are at risk to develop disease progression or a nonMC-lineage haematopoietic neoplasm. Little is known,(More)
Differentiation between asymptomatic sensitization to fungi and clinically relevant allergy is difficult. The aim of this study was to assess the value of nasal provocation with fungal allergens in the diagnosis of allergic rhinitis with special attention to the late phase of monitoring. Eighteen patients with allergic rhinitis and confirmed sensitivity to(More)
BACKGROUND Venom immunotherapy (VIT) enables longtime prevention of insect venom allergy in the majority of patients. However, in some, the risk of a resystemic reaction increases after completion of treatment. No reliable factors predicting individual lack of efficacy of VIT are currently available. OBJECTIVE To determine the use of gene expression(More)
BACKGROUND Diffuse cutaneous mastocytosis (DCM) is an extremely rare disease characterized by mast cell (MCs) infiltration of the entire skin. Little is known about the natural course of DCM. OBJECTIVES We decided to characterize clinical manifestations, the frequency of MCs mediator-related symptoms and anaphylaxis, risk of systemic mastocytosis (SM) and(More)
INTRODUCTION Symptoms resulting from the activation and release of mediators from the mast cells are observed in about 30% of the patients with mastocytosis. OBJECTIVES The aim of the study was to assess the prevalence of anaphylactic reactions and to identify the risk factors for anaphylaxis in patients with mastocytosis depending on the type of the(More)
